IMPROVEMENT IN HAND-VISES.

Specification forming part of Letters Patent No. 133,17L dated November19, 1872.

To all whom it may concern:

Be it known that I, THoMAs Ovnnron, of Corpus Christi, in the county ofNueces and State of Texas, have invented a new and useful Improvement inCombination Hand-Vise, of which the following is a specification:

The object of this invention is to furnish an implement or tool for theuse of mechanics, which can not only be used as a hand-vise for holdingsmall articles, but which can be attached to bits or angers for gagingthe depth of the hole bored, and also countersinking such hole forscrews.

In the accompanying drawing, Figure 1 is a view of a boring-bit with mycombination vise attached thereto. Fig. 2 is a side view of the visedetached. Fig. 3 is a cross-section of, Fig. 1, givingan edge view ofthe vise.

Similar letters of reference indicate corresponding parts.

A and B represent two jaws joined together at one end bya pivot-pin, 0,so that the jaw 13 can play the same as the loose jaw of an ordinaryvise. This loose jaw has a transverse groove, D, so that it will fit toand hold a bit, or to a wire when it is screwed up, as seen in Fig. 3. Eis the vise-screw, by means of which a bit or other article is gripedbetween the jaws. F is an adjustable countersinking-cutter, attached, bya screw, G, to the jaw A.

This cutter is slotted for the screw G, and is confined in a slot in thejaw, so that it keeps its place when cutting, but 'is readily adjusted,by means of the slot therein, to cut more or less, and may as readily beremoved for sharpening or other purposes.

Detached from the bit H the vise is convenient for all the uses to whichhand-Vises are ap plied; and when attached to a boring-bit the depth ofthe hole bored may be gaged exactly and the hole countersunk for awood-screw 0r bolt-head, or left untouched by the cutter, as may bedesired. I is a slot in the screw-head, for convenience in setting saws.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1.- The improved hand implement herein described,consisting of the jaws A B, hinged together, the thumb-screw E, and thecountersink cutter F, arranged parallel to the transverse groove D, asshown and described, for the purpose specified.

2. The cutter F, arranged in a transverse groove of the jaw A, andprovided with a slot, as specified, whereby lateral movement thereof isprevented and longitudinal adjustment provided for, as set forth.
